Banana Pi Infinity cascade IO expand module - Part# BPI-A-003

DESCRIPTION

Product Overview：This module is designed specifically for the Banana Pi IO expansion modules, which can effectively solve the banana send IO port connection limit. The module uses four 74HC595 chips to expand 32 IO ports. As shown above, the top of the module will expand the IO of Banana Pi again and can be cascaded for more IO expansion modules. It can theoretically have unlimited expansion ports.
